Influence of pipe geometric deviation on bristled in-pipe mobile robot locomotion [PDF]
International Journal of Advanced Robotic Systems, 2018 This article deals with the analysis of geometric deviations influence on in-pipe robot locomotion, which uses the principle of friction difference principle. Bristles are as carrying elements. They are mounted as cantilever beams at angle to robot body.

An In-Pipe Mobile Robot Using Electro-Conjugate Fluid
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011 An electro-conjugate fluid (ECF) is a kind of functional fluid, which produces a jet flow (ECF jet) when subjected to high DC voltage. It is known that a strong ECF jet is generated under nonuniform electric field, for example, the field with a pair of ...
